From what I know, these "tarcher style" flies are credited to Ken Iwasama. The keel-weighted, hook point-up, back arched attitude of the nymph creates a realistic profile of a swimming nymph. I just recently began tying these but the pheasant tail and stone fly patterns I have tried are encouraging me to try other patterns with this hook.

These step by step instructions have been provided in good faith by the tyer who uploaded the recipe.

Step 01

Wrap lead turns at the "belly" of this hook. This will turn the hook in the water so that the hook point rides "up". I use 8-10 turns of lead and always coat with super glue or clear nail polish to prevent twisting and more importantly to prevent the lead from leeching any oxidation through your materials after it has been wet and replaced in the box

Step 02

start thread and build up taper at both ends of lead wraps and use touching turns of thread to form a smoothly tapered underbody before guiding thread to hook bend

Step 03

tie in 4-6 pheasant tail feather fibers to form tail

Step 04

wrap pheasant fibers forward to wing case tie-in point - at this point I invert the hook and tie remainder of the fly with the hook point in the "up" attitude of the finished fly

Step 05

tie in turkey wingcase

Step 06

tie in 4-6 strands of peacock herl. twist the herl into a rope and wind the tying thread around the herl rope 10-12 times to strengthen and prevent breaks/renegade strands

Step 07

wind the herl rope forward to build the thorax to desired proportion and tie off/trim waste

Step 08

tie in a "bunch" (8-10) of soft hackle fibers and tie in at the forward end of thorax on each side - align the tips before pulling fibers from the stem and adjust tie-in point to control flare from intersection with thorax
